G'day Mike,
I see you are in South Africa. Good on you for going for your PPL.
I don't know if you are married and/or have children. I am not too sure as to the typical career path in S.A. That is something I would research carefully.
Ask yourself seriously, "Can I afford to be on very low wages/unemployment for the next 5 years?" If the answer is "yes" - Go for it. If the answer is "no". Rethink your options and see if there is another way to realise the dream. (Note, I didn't say "don't do it")
Where many "older" starters fall down is they don't take into account that not every one will sit in a shiny jet within a year of finishing their licence. Come to think of it, many "young" starters with huge loans don't either
Only you can answer these questions. Every one is different. Every country is different too. (In spite of JAR
)
